Nicole Kidman 'Desperately' Wanted Another Child

There are some things that come easily for Nicole Kidman – for instance her ability to tap into a character when the cameras are rolling. But when it comes to motherhood, the Oscar winner – and current best actress nominee – says there is something she has always struggled with.

The mother of four, who just welcomed baby Faith on Dec. 28 via a gestational carrier, says she has "had a roller coaster ride with fertility."

"Anyone that's been in the place of wanting another child or wanting a child knows the disappointment, the pain and the loss that you go through trying and struggling with fertility," the Rabbit Hole actress, 43, tells Australia's 60 Minutes in an interview set to air Sunday night. "Fertility is such a big thing, and it's not something I've ever run away from talking about."
